Crossplay

Is Ico crossplay?

Ico is only released on one platform, so there is nothing to cross-play with.

An action-adventure game in which a boy is abandoned and taken to a massive castle by his people. After exploring it for a while, he meets a girl who speaks a different language than him, then decides to get both of them out of the castle grounds by leading her along, in order to escape the shadow-like creatures that frequently try to kidnap the girl.
